The Sun on May 21, year by year

These positions are all calculated for 12:00 UT. The degree changes between years, even when the sign stays the same.

Positions are shown to the arcminute. A birth before or after noon has a different degree. UT and your local calendar date can differ.

Reading Sun in Gemini

Sun in Gemini is associated with finding purpose through learning and exchanging ideas. Explaining a subject to someone else can help you discover your own position. Curiosity becomes harder to use when every new question interrupts unfinished work.

Gemini is mutable air. Mutable describes adapting to changing information; air concerns thought and exchange. The Sun brings purpose into that process: comparing possibilities becomes part of developing a voice.

Keeping several explanations available can improve a discussion. It can also postpone a decision that needs a clear answer. The interpretive question is when another question adds information and when enough is known to act.

This lesson follows the noon reference position. Confirm your personal Sun sign before applying it to your chart.

The same birthday can produce different charts

The Moon and other planets move independently of the Sun. People born on May 21 in different years can have different Moon signs and planetary aspects.

Birth time and location also change the Ascendant and houses. Astriel uses Placidus: the Sun's house follows its position between calculated cusps. Its zodiac sign alone cannot supply a house number.

If the birth time is unknown, choose that option in the calculator. A date crossing a sign boundary can leave the Sun sign unresolved; houses remain unavailable.
